If you're experiencing login issues with the IHG Hotels & Rewards app, here are the main troubleshooting steps you can take:

- Check Your Internet Connection: Ensure you have a stable internet connection. Try toggling airplane mode on and off, switching between Wi-Fi and mobile data, or restarting your router if necessary12.
- Update the App: Make sure you have the latest version of the IHG Hotels & Rewards app installed. Updates often fix bugs or compatibility issues12.
- Clear Cache and Data: Go to your device’s settings, find the IHG app in the apps manager, and clear its cache and data to remove any corrupted files12.
- Force Stop and Restart the App: On your device, force close the app and reopen it. This can resolve temporary glitches2.
- Reinstall the App: Uninstall the app completely and then reinstall it from your device’s app store12.
- Reset Your Password: If you suspect an account or password problem, use the “Reset Password” link on the IHG sign-in page. Enter the email address associated with your account to receive a password reset email, and follow its instructions6.
- Check for System-Wide Issues: Sometimes, login problems are caused by IHG’s own system maintenance or server issues. If none of the above steps work, it may be necessary to wait and try again later. Checking online forums or contacting IHG customer service can help you confirm if there's a wider outage or maintenance window affecting many users35.

If these steps do not resolve your issue, you can:
- Try logging in from a different device or network, as sometimes issues are device- or region-specific45.
- Contact IHG customer service via their official help channels for further support, especially if you suspect your account may have been flagged or locked7.

These troubleshooting steps address the most common causes for login failures and other technical problems with the IHG Hotels & Rewards app.
